Axial mixture characterization is a widespread problem in granular particle blendingprocesses such as in an horizontal drum mixer. The homogeneous mixture of particles isobtained by blending the particles via rotating paddles in a fixed cylindrical drum. Thisproblem, common to many technological devices, is crucial in the manufacture of abroad variety of industrial products, such as polypropylene. The granular flow behaviorin these systems is still poorly understood and the numerical study of suchconfigurations receives increasing academic and industrial attention. In this paper, astudy is conducted to investigate the effects of different aspects of the reactor design onthe axial transport of monodisperse, uniform density and spherical polypropyleneparticles. Results show that principally the shape of the paddles is the important designconsideration to enhance the axial transport of particles.
